It will not make your hair thicker or thinner. it will only do that if you over process your hair.
the extra oxygen atom also makes hydrogen peroxide more reactive than water. hydrogen peroxide reacts readily with chemical pigments that give materials their color. this process which is called bleaching can make stained teeth white or turn brown hair blond.
First, hydrogen peroxide you buy at the store is damaging for your hair. Second ,it is not the same as peroxide developer in hair dyes. Third, opening the hair shaft will make your color fade faster. Plus it could change the color of the dye you are putting on. The question was true. Yes hydrogen peroxide opens the cuticle of the hair to allow the dye to penetrate it. Peroxide is an alkaline substance with a base of about 9. It opens the cuticle so that the colour can be deposited in the hair. If you didn't use peroxide your colour wouldn't last long.
Darker hair color helps to hide damage, frizz, fly-aways, dryness, and may even help to make the hair appear thicker and fuller.
Volume 10 peroxide is generally used for deposit-only color, while volume 20 peroxide can lighten hair by one to two shades. If you're looking to significantly lighten your hair color, volume 20 is more effective than volume 10. However, the degree of lightening also depends on the hair's starting color and condition. Always consider a strand test to see how your hair reacts.
Shaving does not "make your hair grow back thicker".
no it makes your hair lighter

No it just make your hair shorter. :D
If you got your hair cut in layers it would seem thicker.
Nothing that you can put on from the outside will make your hair grow thicker. (With the possible exception of Minoxidil.)
add more hair to your bangs :)
You can make the color safe bleach by adding peroxide with water.
